Private AI chatbot with agents, voice cloning, and new TTS voices (Qwen 3 TTS, CostVoice, VibeVoice). Chat, transcribe, research, and store models your way.
Private AI chat, voice cloning, meeting transcription, web research, and agent workflows on your Mac, iPad, and iPhone. Run models locally or connect to cloud providers when you choose.
TALK, TRANSCRIBE, AND LISTEN
Turn voice into useful text, then turn answers back into speech when you want to listen instead of read.
• Three new TTS engines: Qwen 3 TTS, CostVoice, and VibeVoice
• Clone your voice and use it across multiple TTS engines
• Record meetings, lectures, interviews, and voice notes
• Import audio files and generate fresh transcripts
• Create natural speech with Apple voices, Kokoro, PocketTTS, or the new engines
• Export transcripts as text, subtitles, or markdown
Perfect for: meetings, lectures, research interviews, quick voice notes, and hands-free review.
AI WORKFLOWS YOU CAN SHAPE AS YOU GO
Real work rarely follows a straight line. Fork, copy, or export any conversation thread from the exact message that matters.
• Fork conversations mid-chat without losing the original
• Copy or export full threads for sharing or keeping records
• Long conversations stay fast — less lag as history grows
• Build subagents for research, writing, coding, analysis, or planning
• Run specialist agents on complex work and bring their results back into one conversation
• Switch models and tools as your task changes
PRIVATE BY DEFAULT
Your conversations, documents, transcripts, and local model runs stay on your device unless you choose to use an online provider.
• Run local models such as Llama, Gemma, Phi, Qwen, DeepSeek, and more
• Choose where models are stored — internal storage, external drive, or a shared volume
• Analyze sensitive documents offline
• Build searchable knowledge libraries for projects and research
• Connect to cloud providers only when you need them
WEB RESEARCH AND ACTIVE TOOLS
Give your AI access to current information when a task needs more than the model already knows.
• Search the web from inside a conversation
• Let the browser agent open pages, read sites, and gather information
• Pause browser work, adjust the task, or take over manually
• Use tools for calculations, network requests, document analysis, and research workflows
